“SS Rigid/Rigid”

The Good: Geometry: HA is 70 degrees with short chainstays and Reynolds tube set .

The Bad: grips and pedals

Overall Review:

Ok I'm riding a SS bike for the fall and winter portion of this year. I chose the Unit because of its geometry and because its steel. It turns out that lot of what you hear about SS is not that far from fiction as you might think. Update 2 months later. This bike has become the stand out bike of my bikes. I grab it for more often than not when going to ride anywhere.  It will never match a suspension bike in a DH trail but have been super surprised that my Strava speeds for complete rides( up and down) are really close.  Little to no maintenance, wheels are still true cheap and you feel manly riding it...hahaha

5 months later update

This is now my main ride.  I never thought that a SS rigid would be my main training bike.  I got it thinking I'd ride it here and there in the mud and bad conditions to save my suspension and drivetrain.  Spring is here and I'm still hustling this thing even though the trails are dry.  It isn't for every trail obviously but 90% of them.  Love it.  My fitness has improved and when I am on my trail bike, it can be ridden harder, longer and with more than wild abandon.
